Birth certificate help

Hi all, I need your help. We adopted in August and I cannot find nor get the birth certificate anywhere! I need this for many reasons. Number one being to get her a ss # and two to finally file taxes and adoption tax credit. So I adopted in Town A seems like Town A never filed her birth certificate with my town, Town B. neither Town A or B have a BC on record. The states vital statistics office doesn't have it either. I've been calling and hounding Town A and they said they're on it. it's been 6 months!, Now what?
